I have heard some talk on http://tvbythenumbers.zap2it.com/tag/csi-ratings/ This is the last season. I would love a Grissom appearance. He still is one of my all time favorite tv characters, and I never got over him leaving. I think a lot of what I loved about Gregory House was the antisocial behavior based on Grissom. I would love a finale scene with the whole original team as their first beer together.
